Abstract
The mixed refrigerant composition according to embodiments of the present disclosure includes carbon dioxide (R-744), trifluoroiodomethane (R-13I1), and 1,1-difluoroethane (R-152a), wherein a sum of contents of the trifluoroiodomethane (R-13I1) and the 1,1-difluoroethane (R-152a) based on a total weight of the mixed refrigerant composition may be 60 wt. % or more and less than 100 wt. %. Accordingly, environmental pollution caused by the mixed refrigerant composition may be suppressed, and the cooling performance of the mixed refrigerant composition may be improved.
Claims17
A mixed refrigerant composition comprising carbon dioxide (R-744), trifluoroiodomethane (R-13I1), and 1,1-difluoroethane (R-152a),
- wherein a sum of a content of the trifluoroiodomethane (R-13I1) and a content of the 1,1-difluoroethane (R-152a) based on a total weight of the mixed refrigerant composition is 60% by weight or more and less than 100% by weight.
A mixed refrigerant composition consisting essentially of:
- carbon dioxide,
- trifluoroiodomethane, and
- 1,1-difluoroethane,
- wherein a sum of a content of the trifluoroiodomethane and a content of the 1,1-difluoroethane based on a total weight of the mixed refrigerant composition is 60% by weight or more and less than 100% by weight,
- wherein the content of the carbon dioxide based on the total weight of the mixed refrigerant composition is greater than 0% by weight and 40% by weight or less,
- wherein the content of the trifluoroiodomethane based on the total weight of the mixed refrigerant composition is 35 to 80% by weight, and
- wherein a ratio of the content of the trifluoroiodomethane to the content of the carbon dioxide based on the total weight of the mixed refrigerant composition is 5 to 80.
